Device and Method for Reshaping the Gable Surfaces of Packages with a Slanted Gable

Abstract

The invention relates to a device (24, 25) for post-forming the gable surfaces of packaging (16) with a diagonal gable, comprising: a conveying device (19) with cells (20) secured thereto for receiving the packaging (16) and for transporting the packaging (16) along a transport direction (T), at least one gable folder (27) for folding a fin seam (17) in the gable region of the packaging (16), and at least two lug folders (28A, 28B) for folding lugs (15) in the gable region of the packaging (16). Both the gable folder (27) and the lug folders (28A, 28B) are movably mounted relative to the conveyor device (19) and the packaging (16) transported therewith. The invention additionally relates to a method for post-forming the gable surfaces of packaging (16) with a diagonal gable. The aim of the invention is to maintain and / or correct the shape of the gable for packages with a diagonal gable. According to the invention, this is achieved in that at least one forming tool (29) for post-forming the fin seam (17) is provided in the gable region of the packaging (16), and the forming tool (29) is movably mounted relative to the conveyor device (19) and the packaging (16) transported therewith.

AI Technical Summary

Benefits of technology

The invention is a device and method for reshaping the fin seam and gable surface of packages. The device includes a forming tool that is mounted in a movable manner relative to the packages. This allows the tool to reshape the fin seam and gable surface without moving the package, which makes it easier to fill and close the package. The method also includes steps to ensure that the forming tool does not reshape the package too close to the folding of the gable and ears, which could cause the adhesion process to be incomplete and the ears to come away from the package again. Overall, the invention improves package reshaping efficiency and ensures a better quality package.

Problems solved by technology

When manufacturing packages of this type, there is a challenge of creating protruding regions such as seams or “ears” on the package.

In these packages, the creation of protruding regions is particularly difficult as it is often not the fin seam but rather the rear edge of the gable which forms the highest point of the package in slanted gable packages of this type.

This leads to the fin seam being more difficult for tools to access.

In particular, the fin seam cannot be applied by a fixed tool which the package passes in these types of packages.

An uneven gable surface is not only visually unacceptable, but also makes it difficult to subsequently apply further elements, for example dispensing elements with screw caps.
